multiline

问题 I am having some problems with deleting everything after the first occurrence of a pattern in R. I have imported the data with paste(readLines(url), collapse="\n") .

I want to remove everything after the first occurrence of </table> . What I want to see is; \"id=\"fruit_info\">\n<tr class='thead'>\n<th colspan=2>Strawberries</th> The methods I am trying do

问题 WRT Any Future Plans for Multiline Java String. How difficult is it to write a utility that does the following? @AllYouCanEatText(return="query") private String getQuery(String empid, String[] columns) { String query; /* SELECT ${columns} FROM Employees WHERE empid = ${empid} ; */ return query; }; Of course, before I jump in front of the barrel, I should have asked - Is such a utility already available? If so, where? The issue at hand is actually - how do I read the comments section in

问题 I was working on a Swift tutorial and found that Swift has a strange way to handle multi-line statement. First, I defined some extension to the standard String class: extension String { func replace(target: String, withString: String) -> String { return self.stringByReplacingOccurrencesOfString(target, withString: withString) } func toLowercase() -> String { return self.lowercaseString } } This works as expected: let str = "HELLO WORLD" let s1 = str.lowercaseString.replace("hello", withString

问题 I can't figure out how to make textpad perform a regular expression that extends multiple lines. I tried using perl syntax with /myregex/m with m as a modifier but that didnt' work. I can't see a checkbox or anything in the editor to tell it to do multiline. anyone have any ideas? 回答1: It is entirely possible, and simple :) You just use \n This search: we\nwill Matches the end of line 1 and the start of line 2 in this dummy text: this is a test and we will see if it matches multiple lines.

问题 I like to parse strings ad hoc in Python by just pasting into the interpreter. >>> s = """Adams, John ... Washington,George ... Lincoln,Abraham ... Jefferson, Thomas ... """ >>> print "\n".join(x.split(",")[1].replace(" ", "") for x in s.strip().split("\n")) John George Abraham Thomas This works great using the Python interpreter, but I'd like to do this with Haskell/GHCi. Problem is, I can't paste multi-line strings. I can use getContents with an EOF character, but I can only do it once

问题 In the spirit of this question: https://stackoverflow.com/questions/1886966/java-string-declaration-occupying-multiple-lines will there be any plans in any future version of Java to allow string continuation in the java scource?

问题 This question already has answers here : SASS indented syntax on multiple lines? (2 answers) Closed 4 years ago . I couldn't figure out that from SASS documentation. For example I would like to use Compass mixin with 5 parameters: =link-colors(!normal, !hover = false, !active = false, !visited = false, !focus = false) I would like to declare 5 constants with semantically understandable names like those: !top_line_navigation_link_normal_color = #00c !top_line_navigation_link_hover_color = #0cc

问题 This question already has answers here : Creating multiline strings in JavaScript (37 answers) Closed last year . The question is: What is the JavaScript method to store a multiline string into a variable like you can in PHP? 回答1: If by 'multiline string' you mean a string containing linebreaks, those can be written by escaping them using \n (for newline): var multilineString = 'Line 1\nLine 2'; alert(multilineString); // Line 1 // Line 2 If you mean, how can a string be written across
